Hello, thanks for adding me to this forum. I'm working on the restoration of a '70 Dodge (RV2 system) and ran across a few things I haven't seen before.

First, what is everyone's take on flushing suction-side mufflers? These RV2 systems have big inline mufflers on both the suction and discharge side. They seem totally unavailable as NOS or aftermarket pieces nowadays, but they are important for a factory-correct appearance in this resto. I know the discharge muffler should not be flushed, but what about the suction side?

My second questions is related, because during disassembly, I noted all lines were relatively clean except for the suction line between the evaporator and the muffler. I found a decent amount of dirty oil and rust in that line, but the line from the muffler out to the compressor was clean. All other lines were also clean with no rust and clear oil. Txv was clean, as was the compressor inlet screen. I haven't removed the evap yet and not looking forward to that. Any thoughts on why so much bad stuff in that one line? Thank you.

I usually gut those. It is easier on the ones with a tube that goes straight through - I bore the tube out & run a tube straight through the can & braze the tube to the ends of the can. It still looks OEM for a 100 point car - just a straight through tube in reality.

With the angle fitting on one end a little finesse should get the fitting off of the can. Then silver solder or braze a tube in to the angle block, run the tube through the bored out can, etc.

At least you have rubber lines. It is harder to duplicate the nylon with outer brain Mopar sometimes used.
